iXBT Labs posted a review on the Intel DP55WB "Whitesburg" Motherboard

The only question Whitesburg may start is, "Why is it based on P55 and not H55?" Blame those who decided on the gradual rollout of the LGA1156 platform. As a result of which, P55 PCH was the only available chipset for the first six months. So, if Intel DP55WB remains one of the cheapest in the market, its life cycle will be long. If similar products based on H55 will be cheaper, then there will be no sense in buying this motherboard.
